Greetings Histoland.
I am getting a new Leica TP1050 Processor in a few weeks, to replace my
Shandon Citadel 2000 open processor.  I'd like to know how the
histo-community determines when to change the reagents in the processor, ie
after a certain number of cassettes are processed, or after a certain number
of runs.  I'm also interested in the type of alcohol used in the processors.
I use reagent alcohol from Fisher - it's 90% ethanol, 5% methanol, and 5%
isopropanol.  Thanks.  Jen
